In enzymology, a 2-oxoglutarate carboxylase (EC 6.4.1.7) is an enzyme that catalyzes the chemical reaction

ATP + 2-oxoglutarate + HCO₃- $\rightleftharpoons$ ADP + phosphate + oxalosuccinate

The 3 substrates of this enzyme are ATP, 2-oxoglutarate, and HCO3-, whereas its 3 products are ADP, phosphate, and oxalosuccinate.

This enzyme belongs to the family of ligases, specifically those forming carbon-carbon bonds. The systematic name of this enzyme class is '. Other names in common use include oxalosuccinate synthetase', carboxylating factor for ICDH (incorrect), CFI, and OGC.
